Radxa NIO 5A credit card-sized Mediatek Genio 520 SBC showcased at Computex 2025

Radxa NIO 5A is an upcoming Mediatek Genio 520 SBC in credit card/Raspberry Pi form factor that should offer a more affordable entry into the MediaTek Genio family than Radxa Nio 12L equipped with a powerful Mediatek Genio 1200 SoC.

There’s no public information on the web about it, but I was sent some photos of the board from Mediatek’s booth at Computex 2025, and we know it’s powered by the Genio 520 octa-core Cortex-A78/A55 SoC with a 10 TOPS AI accelerator and comes with “large memory and high-capacity storage”. Let’s see if we can derive more detailed specs from the photos and other public information about the SoC.

Radxa NIO 5A specifications (preliminary):

• SoC – Mediatek Genio 520 (MT8371)
  • CPU – Octa-core processor with
    • 2x Arm Cortex-A78 up to 2.2 GHz (Commercial) or 2.0 GHz (Industrial)
    • 6x Arm Cortex-A55 up to 2.0 GHz (Commercial) or 1.8 GHz (Industrial)
  • GPU – Arm Mali-G57 MC2 up to 880 MHz with support for OpenGL, OpenCL, Vulkan
  • VPU
    • Video Encoding – 4K30, HEVC/H.264
    • Video Decoding – 4K60, HEVC/H.264
  • AI accelerator – 8th Generation NPU delivering up to 10 TOPS
• System Memory – Up to 16GB LPDDR5 @ 6400MT/s (the sample above features an 8GB SK Hynix H58G56AK6B LPDDR5 chip)
• Storage
  • MicroSD card slot (TBC)
  • Optional UFS 3.1 or eMMC 5.1 flash
  • SPI flash footprint
• Video Output – HDMI port up to 4Kp60 (if eDP to HDMI bridge used)
• Audio – 3.5mm audio jack
• Camera I/F – MIPI CSI connector up to 16 MP camera
• Networking
  • Gigabit Ethernet RJ45 port with optional PoE via 4-pin header
  • WiFi 6E and Bluetooth 5.2 wireless module (not solderable on the sample at Computex 2025) and two u.FL antenna connector
• USB
  • 2x USB 3.2 Gen-1 ports
  • 2x USB 2.0 ports
• Expansion
  • 40-pin Raspberry Pi-compatible GPIO header
  • 16-pin PCIe Gen2 x1 FFC connector compatible with the Raspberry Pi 5 PCIe FFC connector
• Misc
  • Power, Recovery, and MaskROM buttons
  • Fan connector
• Power Supply – 5V via USB Type-C port
• Dimensions – 85 x 56 mm

The Mediatek Genio 520 SBC is designed for edge computing, intelligent security, Smart Retail, cloud computing, and Smart Home applications. The Genio 520 was announced along with the Genio 720 last March, so it’s very new, and it will likely take a while before the board is released.

While we don’t have anything specific about software/OS for the Radxa NIO 5A, Mediatek mentions support for Android, Yocto Linux, and Ubuntu OS for the Genio 520/720, and NVIDIA TAO Toolkit for the 10 TOPS NPU.

We don’t have pricing information, but we can always speculate. The Radxa NIO 12L SBC starts at $99 with 4GB RAM and 64GB UFS storage, while the more compact Radxa ROCK 5C credit card-sized SBC with a Rockchip RK3588 SoC and 4GB RAM goes for $59.90, so I’d expect the Radxa NIO 5A to be around $70 with 4GB LPDDR5 and no storage. Only time will tell.
